Abstract

A method for producing a thin panel liquid crystal display system (20) for producing images comprising providing a mother glass (32) having at least two active glass substrates (34) therein, adhering the mother glass (32) to a handle substrate (38) to provide strength and rigidity to the mother glass (32), printing said active glass substrates (34) with grid lines, cutting the mother glass (32) between the active glass substrates (34), separating the active glass substrates (34) from one another, placing two active glass substrates (34) in parallel with one another, disbursing a plurality of glass beads on one of the active glass substrates (34), injecting liquid crystal display material between the active glass substrates (34), sealing the active glass substrates (34) together, and separating each of the active glass substrates (34) from the handle substrate (38).

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A method for producing a thin panel liquid crystal display comprising: providing a thin panel glass substrate;   adhering said glass substrate to a handle substrate to provide rigidity to said glass substrate; and   printing said glass substrate attached to said handle substrate with grid lines to form an active glass substrate.   
     
     
       2. The method for producing a thin panel liquid crystal display as recited in claim 1 wherein said active glass substrate is a top panel and further including the steps of: providing a second thin panel glass substrate, said second thin panel glass substrate being a bottom panel;   adhering said bottom panel to a handle substrate to provide rigidity to said bottom panel;   printing said bottom panel with grid lines;   placing said top panel and said bottom panel in parallel with one another; and   sealing said top panel to said bottom panel.   
     
     
       3. The method for producing a thin panel liquid crystal display as recited in claim 2 further including, before the step of placing said top panel and said bottom panel in parallel with one another, the step of disbursing a plurality of glass beads on one of said panels. 
     
     
       4. The method for producing a thin panel liquid crystal display as recited in claim 2 further including, before the step of sealing said top panel to said bottom panel, the step of injecting liquid crystal display material between said top panel and said bottom panel. 
     
     
       5. The method for producing a thin panel liquid crystal display as recited in claim 1 wherein said active glass substrate is part of a mother glass which includes a plurality of active glass substrates. 
     
     
       6. The method for producing a thin panel liquid crystal display as recited in claim 5 further including the steps of: cutting said mother glass between each of said active glass substrates;   separating each of said active glass substrates from said handle substrate; and   reusing said handle substrate.   
     
     
       7. The method for producing a thin panel liquid crystal display as recited in claim 5 further including the steps of: cutting said mother glass and said handle substrate between each of said active glass substrates; and   separating each of said active glass substrates and handle substrates from adjacent active glass substrates and handle substrates.   
     
     
       8. The method for producing a thin panel liquid crystal display as recited in claim 2 further including, before the step of placing said top panel and said bottom panel in parallel with one another, the steps of: separating said top panel from said handle substrate; and   separating said bottom panel from said handle substrate.   
     
     
       9. The method for producing a thin panel liquid crystal display as recited in claim 2 further including, after the step of sealing said top panel to said bottom panel, the steps of: separating said top panel from said handle substrate; and   separating said bottom panel from said handle substrate.   
     
     
       10. The method for producing a thin panel liquid crystal display as recited in claim 1 wherein said handle substrate further includes a thin panel cold cathode fluorescent lamp. 
     
     
       11. The method for producing a thin panel liquid crystal display as recited in claim 1 wherein said handle substrate further includes a light guild. 
     
     
       12. A thin panel liquid crystal display system comprising: a top panel having a thickness of less than 0.3 millimeters and greater than 0.1 millimeters; and   a bottom panel disposed in parallel with said top panel, said bottom panel having a thickness of less than 0.3 millimeters and greater than 0.1 millimeters.   
     
     
       13. The thin panel liquid crystal display system as recited in claim 12 further including a layer of liquid crystal material disposed between said top panel and said bottom panel. 
     
     
       14. The thin panel liquid crystal display system as recited in claim 12 wherein said thin panel liquid crystal display is incorporated into a portable computer. 
     
     
       15. A method for producing a thin panel liquid crystal display comprising: providing an glass substrate having a thickness of less than 0.7 millimeters and greater than 0.1 millimeters;   adhering said active glass substrate to a handle substrate to provide rigidity to said active glass substrate; and   printing said glass substrate attached to said handle substrate with grid lines to form an active glass substrate.   
     
     
       16. The method for producing a thin panel liquid crystal display as recited in claim 15 wherein said glass substrate is a top panel and further including the steps of: providing a bottom panel having a thickness of less than 0.7 millimeters and greater than 0.1 millimeters;   adhering said bottom panel to a handle substrate to provide rigidity to said bottom panel;   printing said bottom panel substrate attached to said handle substrate with grid lines to form an active glass substrate;   placing said top panel and said bottom panel in parallel with one another; and   sealing said top panel to said bottom panel.   
     
     
       17. The method for producing a thin panel liquid crystal display as recited in claim 16 wherein said top panel and said bottom panel each have a thickness of less than 0.3 millimeters.
